Mark, yes I did use bluetooth when I first got the 570 but like yours it kept losing it. I would connect back up and a day or so later it was gone again. I use the lead all the time and got used to it now. Since new system has come out I think its bloody fabtastic now I've got the hang of it. I uploaded disc 1/2013 today and then the latest internet updates came about 10 minutes later. These I update about once a month as I queue them up to load all in one go.
